**6 tools: 1 do something that can't be undone, 4 change things and 1 only read.**

## Exfil surface

No private-data -> untrusted-input -> outbound path in this server alone: no tool is tagged private-data or untrusted-input.

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | none |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | none |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | `mcp__agtrepo-memory__send_feedback` |

## Findings

No check matched anything in these tool definitions.


## Can't be undone (1)

Sends, pays, publishes or merges: once done, it cannot be taken back. Claude Code: ask.

### `send_feedback`

- The name "send_feedback" says "send": a word for sending, and what is sent cannot be taken back.
- Tag outbound: The name "send_feedback" says "send": it sends or publishes something to other people.

Description, as the server wrote it:

```untrusted-server-text
Free. Sends a message to the human operators of this service: a bug report, a problem with these tools or the documentation, or a suggestion. It is read by people, not processed by software, and nothing is returned beyond an acknowledgement. Do NOT use it for status updates, progress notes, task narration, error logs, or as a fallback when another tool is unavailable or a payment cannot be made -- it cannot complete, retry or work around any task. Name is optional (omit for anonymous feedback); message is limited to 1000 characters.
```

## Changes things (4)

Creates or changes something that can be changed back. Claude Code: ask.

### `extend_memory`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
Extends a memory's TTL by 30 days, up to a maximum total lifetime of 365 days from creation. Requires x402 payment. An expired memory is deleted and cannot be extended.
```

### `register_key_release`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
Free. Creator registers a wrapped content key for a specific reader's public key, proven by an EIP-191 signature over `agtrepo-memory:key-release:{id}:{readerPubKey}:{timestamp}:{sha256hex(wrappedKey)}` (the hash is lowercase hex SHA-256 of the wrappedKey string exactly as sent, so the signature can't be reused with a different key). `{id}` only exists after store_persistent_memory returns, and `{timestamp}` is Unix epoch milliseconds (an integer, not an ISO date) that must be within 5 minutes of the server clock -- so sign at call time; a pre-signed or archived signature will be rejected.
```

### `share_memory_key`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
Free. Releases a previously creator-registered wrapped key to a reader, or the raw content key for a public document.
```

### `store_persistent_memory`

- The name "store_persistent_memory" says "store": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Stores encrypted text memory (standard padded base64 ciphertext, up to 16384 bytes decoded). Requires x402 payment. Returns the memory's id.
```

## Only reads (1)

Looks things up and changes nothing. Claude Code: allow.

### `read_memory`

- The name "read_memory" says "read": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Reads an encrypted memory by id. Requires x402 payment. 70% of the fee accrues to the memory's creator.
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `agtrepo-memory`:

```json
{
  "permissions": {
    "allow": [
      "mcp__agtrepo-memory__read_memory"
    ],
    "ask": [
      "mcp__agtrepo-memory__store_persistent_memory",
      "mcp__agtrepo-memory__extend_memory",
      "mcp__agtrepo-memory__share_memory_key",
      "mcp__agtrepo-memory__register_key_release",
      "mcp__agtrepo-memory__send_feedback"
    ],
    "deny": []
  }
}
```

Capability tags behind the rules (a read tagged outbound is asked about):

- `mcp__agtrepo-memory__send_feedback`: outbound

## Remote posture

What an anonymous client saw at the remote endpoint, last 2026-10-22T14:55:51.976Z, unchanged since 2026-10-22T14:55:51.976Z. No credentials were sent and no tool was called. Values are shown as the endpoint returned them. Method: https://anlyon.dev/methodology#remote-posture

| Fact | Observed |
| --- | --- |
| Reachable | `yes` |
| HTTP status of an anonymous initialize | `200` |
| tools/list served without credentials | `yes` |
| Tools that change things, listed without credentials | `5` |
| Protocol version | `2025-06-18` |
| WWW-Authenticate on 401 | `not observed` |
| resource_metadata in WWW-Authenticate | `none` |
| RFC 9728 protected resource metadata | `none` |
| Authorization servers | `none` |
| Legacy HTTP+SSE transport | `no` |
| Dynamic client registration | `not observed` |
| Client ID metadata documents | `not observed` |

- **high** Tools that change things, listed to anyone ([unauth-remote-writes](https://anlyon.dev/methodology#unauth-remote-writes))

```untrusted-server-text
The endpoint served tools/list without credentials, and the list has 5 tools that change things (1 irreversible, 4 write). Whether a call also works without credentials was not tested: tools are never called.

https://agtrepo.com/mcp: tools/list returned 6 tools to an anonymous client, including send_feedback (irreversible), store_persistent_memory (write), extend_memory (write), share_memory_key (write), register_key_release (write)
```
